- AC power adapter for Canon Canoscan 9900F 9900 Scanner
Use supplied AC adapter only. Place the scanner on an even and flat surface.
Tilted or uneven surface may cause a mechanical problem. Keep the outer carton and packing material for future shipment. Unlocking the Lock Switch Scanning unit is locked by the lock switch to prevent a damage during transport. Ensure to lock the lock switch during transport. Install the device driver before connecting the cables. IEEE Cable is not included. Scanning Original 1 Place an original face-down on the document glass by aligning its top edge with the alignment mark.
Scanning Film 1 Slide the protective sheet up and remove it from the document cover. Figure 2 Insert the film into the film guide. Clean the document Canon CanoScan 9900F Scanner according to the following Canon CanoScan 9900F Scanner.

Wipe a dirt off the document glass with the cloth. Document Scanning Sequence A. Functions The scanner is composed of three systems including optical system, image processing system, and control system.
Outline Figure is an electric system circuit diagram. The scanner is not equipped with CPU. The device driver with a control program installed in the host computer functions as CPU. The ASIC controls the whole electrical circuits and image processing of the scanner.
Stores the image data when scanning. Document Scanning Sequence 1. Outline The optical system consists of the scanning lamp, lens and mirrors. When scanning a reflective materials such as papersthe original is exposed to the light of the scanning lamp in the scanning unit. Canon CanoScan 9900F Scanner reflected light of the original forms an image on the photosensitive device, CCD charge-coupled device via lens and mirrors.
The transmitted light forms an image on CCD.

Lamp Lighting Circuit 1. The scanner is equipped with a lamp OFF function for energy saving.
A built-in timer automatically turns off the lamp if no scanning command is sent from the host computer for a certain period of time. Setting up of the timer is conducted by the device driver.
Light of the FAU lamp is converted into a flat light source by a light guide plate. The light is diffused by the1st diffusive film, the luminous intensity enhancement film and the 2nd diffusive Canon CanoScan 9900F Scanner.
Light transmitted the transparent plate all has the same luminous intensity as a result. Light transmits a film and is focused Canon CanoScan 9900F Scanner the CCD in the scanning unit. Light transmits a film via the1st diffusive film, the luminous intensity enhancement film, the 2nd diffusive film and the transparent plate. Outline When scanning a film, it is difficult to obtain a clean image because of dirt and scrach on the Canon CanoScan 9900F Scanner.
This data is compared to the full image data scanned by the FAU lamp, and Canon CanoScan 9900F Scanner overlap data that is of scratches and dirt is deleted. The other scanned data of the film compensates for the deleted area, and the image without scratches and dirt is reproduced. If there light sources are used under the same optical system, the image will be out of focus Figure This unit is placed between the CCD and lens and is consists of a refraction glass that changes the refractive index of light and electromagnetic switch that change the position of the refraction glass.
First, scan a film with light of the FAU lamp transmitting the refraction glass.
